Diplodocus and close relatives such as Apatosaurus and Barosaurus were the dominant plant eaters among the late Jurassic dinosaur communities of North America. Five almost complete skeletons of Diplodocus have been found in the United States from Colorado, Utah, Wyoming and Montana. At the end of the 19th century hundreds of crates containing bones of the “Double-beam Lizard” were sent back to the Carnegie Museum in Pittsburgh, Pennsylvania. You can see beautiful replicas of the complete skeleton in major museums throughout the world. Diplodocus was a very long, quite slim sauropod. It had a remarkably long neck and a long, slender, whip-like tail. It stood tail, on long front legs, and it could stretch its long, horse-like head up to reach 10-12 m above the ground in search of soft vegetation from the treetops. The peg-like teeth occur only in the front of the mouth. Surprisingly, compared with giant sauropods such as Argentinosaurus, Diplodocus was a lightweight. Huge tendons attached to its backbone enabled Diplodocus to hold both its neck and its tail high off the ground.
